Is there a barrier to us using non-core perl modules, in this case Text::Template?
I think it would be a tremendous improvement in readability and maintainability over our current series of print statements, some multiline, some not. The module itself works like this https://www.perlmonks.org/?node_id=33296 Some other digging around shows that the module has been around since 1996 (Perl5 was 1994) and hasn't had a feature update (or any update for that matter) since 2003. So it should meet our baseline 5.14 requirement, which came out in 2011. I'm happy to proceed with a proof-of-concept so that people can see the costs/benefits, but wanted to first make sure it wasn't a total non-starter.
